Could anyone please explain to me how the dissipation of energy works????

Thank you in advance!

OK, so in class the teacher talked about something that had to do with a bouncy ball. Every time the ball bounces back up, it's lower than it was before, because of the gravity. But somehow the gravity makes the ball hot? But then what happens the the ball once it's stopped bouncing completely? It can't just stay hot forever! Where does the energy go then???

The ball does not get hot because of gravity. It gets hot because it strikes a surface which changes some of its potential energy into heat. It bounces lower each time because the potential energy cannot be completely returned to the ball itself, some is transferred into heat. When it finally comes to rest, the ball will be warmer, but then this heat will be transferred to colder objects (floor, air) because heat always flows from warm to cold. Eventually it will be the same temperature as its environment.

so the reason why the ball slowly does not go as high is because all the PE of the object is converted to heat and other forms of energy, that is why the ball heats up.

Energy is like matter, it is never destroyed, just transferred and transformed. There is only 2 forms of energy potential and kinetic, they switch between eachother.
